In this study, simple, fast and reliable cyclic voltammetry (CV), linear sweep voltammetry (LSV), square wave voltammetry (SWV) and differential pulse voltammetry (DPV) methods were developed and validated for determination of bosentan in pharmaceutical preparations. The proposed methods were based on electrochemical oxidation of bosentan at platinum electrode in acetonitrile solution containin...

Atomic emission spectroelectrochemistry (AESEC) combined with linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS) provided insights on both active passive dissolution of Ni-Fe-Cr-Mn-Co multi-principal element alloy. Elemental rates measured by AESEC during open circuit experiment were in agreement those extrapolated from AESEC-LSV indicated element-specific tendencie...

ACI Rossignol is composed of teams from LIF (UMR 6166), LSV (UMR 8643), INRIA Futurs (Projet Comète and projet SECSI) and Verimag (UMR 9939). The research topic of the action is ccryptographic protocol verification. Two general meetings have been held and additional meetings between sites have been organized. Futhermore the action has organized a Spring School on formal aspects on Security (Sec...

Bioelectricity production from a phytoplankton, Chlorella vulgaris, and a macrophyte, Ulva lactuca was examined in single chamber microbial fuel cells (MFCs). MFCs were fed with the two algae (as powders), obtaining differences in energy recovery, degradation efficiency, and power densities. C. vulgaris producedmore energy generation per substrate mass (2.5 kWh/kg), butU. lactucawas degraded mo...

Abstract: Since the last decade, unusually high honey bee colony losses have been reported mainly in North-America and Europe. Here, we report on a comprehensive bee pathogen screening in Belgium covering 363 bee colonies that were screened for 18 known disease-causing pathogens and correlate their incidence in summer with subsequent winter mortality. Our analyses demonstrate that in addition t...

OBJECTIVE to determine the patterns of long saphenous vein (LSV) disease in primary varicose veins (VVs). DESIGN a retrospective analysis of venous duplex scans performed on patients referred for treatment of primary VVs. METHODS analysis was made of sapheno-femoral junction (SFJ) incompetence, non-SFJ incompetence, segmental and perforating vein incompetence, distribution of varicosities, ...

Jeans’s (1902 & 1929) gravitational instability criterion gives truly spectacular errors in its predictions of cosmological structure formation according to Gibson’s (1996) new theory. It is suggested that the linear perturbation stability analysis leading to the acoustic Jeans length scale criterion L ≥ LJ ≡ Vs/(ρG) 1/2 is quite irrelevant to gravitational condensation, which is intrinsically ...

Research objective: to determine the characteristics of nutritional status (NS) in women reproductive age with typical clinical signs lichen sclerosus vulva (LSV) using key NS parameters. Materials and methods. The study included 75 average 31.3 ± 1.3 years. 50 were diagnosed LSV disorders (main group), 25 practically healthy (control group). Information about all patients was collected through...
